I popped into the Science Reference Library, off Chancery Lane in London, and looked at their material.
They have one section of the library devoted to Pollution and Contamination, which is about 12 feet high and 9 feet wide and full of books !
If you would like me to I can try and get a listing from them of the books they hold that may be of use to you in your search.
In the interim you could have a look at Robert Dunn's reading list on the Website.
